Common Questions
Can our duct system handle better air filters for vog and spring pollen?
Your galvanized sheet metal ductwork with external insulation is robust and typically has lower static pressure than flex duct. This allows for the use of a MERV-13 filter to capture vog particulates and March pollen peaks without overtaxing the blower motor. A static pressure test during service can confirm your system's capacity for upgraded filtration.
Our new thermostat is showing an E73 error. What does that mean for us?
An E73 'No power to R wire' alert indicates a break in the 24-volt control circuit between the thermostat and the air handler. In Kalaeloa, this is often caused by corrosion at the contactor in the outdoor unit due to the salt-laden environment. It's a specific failure point that a technician can diagnose and repair quickly to restore system operation.
Is switching from our old electric furnace to a heat pump a good idea for our mild winters?
Absolutely. A heat pump provides efficient electric heat down to our winter lows, operating at 300-400% efficiency compared to the 100% of resistance heat. This drastically reduces consumption during the 5-9 PM utility peak hours when rates are highest. The switch eliminates the standalone furnace, simplifying your mechanical system.
Our AC is from when the house was built. Is it near the end of its life?
A system installed in 1978 is approximately 48 years old, which far exceeds the typical 15-year service life. The primary failure mode here is salt air induced condenser coil corrosion. The aluminum fins and copper tubing degrade from constant exposure to marine aerosols, leading to refrigerant leaks and a complete loss of cooling capacity long before other components fail.
What are the permit and safety rules for a new AC installation now?
All installations require a permit from the City and County of Honolulu Department of Planning and Permitting. As of 2026, systems using A2L refrigerants like R-454B must comply with updated safety codes (UL 60335-2-40). This mandates specialized leak detectors, revised clearance zones, and technician certification to handle the mildly flammable refrigerant safely.
What if our AC stops cooling completely on a hot afternoon? How fast can a technician get to Kalaeloa Heritage Park?
A dispatch from our shop near Kalaeloa Airport (JRF) uses HI-93 (Farrington Highway) for direct access to your neighborhood. For a no-cool emergency, we can typically have a technician on-site within 15 to 25 minutes. We prioritize these calls to prevent heat buildup and humidity damage in your home.
What's the new SEER2 standard, and do the new rebates make an upgrade worthwhile?
The federal minimum efficiency is now 14.3 SEER2, but modern heat pumps easily achieve 18 SEER2 or higher. With Hawaii's electric rate at $0.44 per kWh, the energy savings are substantial. The Inflation Reduction Act's HEEHRA rebates, capped at $8,000, can directly offset the cost of a qualifying high-efficiency system, making the upgrade a strong financial decision.
Why does our AC struggle on days that aren't even record-breaking heat?
Your system was designed for a peak load of 87°F. When ambient temperatures exceed this design temp, which happens regularly, the system cannot maintain the indoor setpoint and runs continuously. The newer R-454B refrigerant has a slightly lower pressure-temperature relationship than older types, which can provide marginal efficiency gains in these sustained high-load conditions.
